Re: SCSI or IDE
About performance - IDE still uses a lot of the CPU, SCSI has it's own
processing power. You can put a lot more disks on a single SCSI
controler, than on a IDE controler, and there (afaik, i could be
mistaken) two drives on one bus cannot work simultaneously and share the
bandwidth (which isn't a problem with SCSI, if you have 160 MB/s bus,
and 3 disks that can make about 40MB/s, you can have all 120MB/s)
And maybe i should say something about the reliability, SCSI disks don't
die that often, compared to IDE drives, while being used a lot 24x7.
